A method for avoiding a network congestion at a network includes an aggregator and a plurality of workers, wherein the plurality of workers share the same bottleneck link to the aggregator. The method includes counting a number of connections between the aggregator and the worker, and adjusting a window size of each of the workers. The window size is based on the number of connections. The method further includes adding an ACK delay to an ACK, and sending the ACK with the window size to the worker. The ACK delay is based on the window size.

Method for avoiding network congestion and an apparatus thereof

An apparatus and method for implementing a vertical handoff between a WLAN and a broadband wireless communication network are provided. The vertical handoff apparatus includes a base station (BS) of the broadband wireless network and at least one access point (AP) of the WLAN within the cell coverage area of the BS, and a switch for forwarding packets between the BS and the at least one AP and processing a handoff between the BS and the at least one AP.
